Insulation work and help navigating Connecticut rebates both feature in customers’ accounts of Eco Energy Guard. The company says it has been in business for 18 years, offers free estimates and serves Bristol, Newington, Farmington, Avon, Plainville, Berlin, Canton and Burlington. It describes itself as an Energize CT partner and says its insulation improvements can help homeowners save up to 20% annually on energy bills. A July 2026 Google reviewer returned to Eco after an earlier insulation project. Following an energy audit in 2025, they needed attic-rafter insulation replaced and floors insulated. They said Bill handled the paperwork for a Connecticut rebate extension and guided them through the rebate process, alongside insulation work they praised. Another customer, writing in May, said Bill explained how to obtain an energy evaluation and helped file for a rebate. That customer also described his attention to a bathroom vent-fan duct issue and thorough cleanup. In a separate May review, a tradesperson praised Bill and his crew for arriving on time, preparing carefully for an insulation installation and respecting the house. A February 2026 customer said Bill quickly provided an estimate and completed basement insulation, leaving clean work. In November 2025, an attic-insulation customer praised the crew’s ability to work around an HVAC unit and ductwork to cover the space, along with Bill’s responsiveness and scheduling flexibility. Google lists a 5-star average from 113 ratings.
After an energy audit last fall, I needed to replace the insulation in my attic rafters and have the floors insulated. I had previously used Eco Energy Guard for another insulation project so called Bill for the attic insulation. I needed to get an extension for the CT rebate since the audit was done in 2025. Bill handled all of the paperwork in order to get the extension. In addition to an outstanding insulation job, Bill guided me through the entire rebate process. The whole experience and result was fantastic.
Bill was extremely helpful and knowledgeable about my house's insulation deficiency. He gave me step by step information about getting an energy evaluation and then helped me to file for the rebate. He also treated my house like it was his own, found an issue with my bathroom vent fan duct, went to the hardware store to get the proper wall outlet and installed it for in incredibly cheap price. Cleaned everything up when they were done like they were never here. Highly recommend!
Bill and his crew showed up on time, and got to work immediately. Their attention to detail during prep work was a testament to the wonderful job they did with their insulation install. As a full time tradesman myself it's always awesome having others here who respect their work, and our house as much as i do. 10/10 would recommend for your insulation needs!
I was looking to find a reliable company to complete insulation work in my basement. While many companies did not even return a call, Bill was quick to provide an estimate and complete the work. Their team was professional and their work was clean. Happy with the service!
Eco did an excellent job on my attic insulation. Bill was very responsive and accommodating to our schedule. They were able to work around the HVAC unit and duct work to get the space 100% covered. I highly recommend Eco!
